The priority at EPRI is to ensure that utilities will have the flexibility of applying a variety of NO/sub x/ reduction technologies to achieve effective control at the lowest possible cost and with the highest possible reliability. The proposed legislation includes requirements for retrofitting abatement technologies on fossil-fuel fired plants built before the New Source Performance Standards (NSPS) went into effect in 1971. NO/sub x/ reduction in US power plants constructed after 1971 has relied on furnaces incorporating combustion modification and/or cleaning of flue gas. EPRI is mounting a demonstration program involving combustion modification technologies that can be retrofitted on the four major pre-NSPS boiler types. Extensive tests on a pilot-scale selective catalytic reduction system for flue gas cleaning are also being sponsored by EPRI using its Arapahoe test facility.
